Mitochondria and Chloroplast The outer layer of the double membrane is much more permeable than the inner layer, which features a number of embedded membrane transport proteins. Enclosed by the chloroplast membrane is the stroma, a semi-fluid material that contains dissolved enzymes and comprises most of the chloroplast's volume. Since, like mitochondria, chloroplasts possess their own genomes (DNA), the stroma contains chloroplast DNA and special ribosomes and RNAs as well.

Difference between Mitochondrial DNA and Chloroplast DNA Both mitochondrion and chloroplast are semi autonomous organelles with DNA. Majority of proteins required for mitochondrion and chloroplast are coded by genes of the nucleus. Only some proteins are coded by the DNA of mitochondrion and chloroplast.

Circular DNA and RNA (Bioinformatics) It should be noted that plasmids most often also have a circular DNA form. As sperm is small and contains mostly DNA, while the ovum is large and contains much cytoplasm containing both mitochondria or chloroplasts, both the chloroplasts and the mitochondria are maternally inherited. mtDNA contains about 20 genes.

What is chloroplast? Best Answer: Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide to produce sugars.hloroplasts are observable morphologically as flat discs usually 2 to 10 micrometer in diameter and 1 micrometer thick. The chloroplast has a two-membrane envelope termed the Inner & Outer membrane respectively. Between these two layers is the intermembrane space.

- Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants, in the chloroplast. In humans, the 16,600 base pairs of mitochondrial DNA encode for only 37 genes.

Are chloroplasts found in animal cells? No, animal cells do not contain chloroplast because chloroplast functions as the source of photosynthesis. Chloroplast is part of the Plastid group, which are specific organelles which specifically function in organic plant organisms. This group, in general, supplies the energy storage and the synthesis of metabolic materials, e.g. photosynthesis.

In a plant cell where in DNA found? Plant cell has nuclear (in nucleus)and extranuclear DNA. Extranuclear DNA is in its mitochondria and Chloroplasts.Mitochondria and chloroplasts are semiautonomous and it is because they have their own DNA, mRNA, tRNA, ribosomes and they replicate by binary fission so they are said to be self governing.

Chloroplast Structure A chloroplast is a type of organelle. Chloroplasts are the site of photosynthesis in eukaryotic cells. Therefore they are only present in photosynthetic cells e.g. plant cells and algae.There are no chloroplasts in animal cells or bacteria cells (bacteria cells are also known as prokaryotic cells and do not contain any membrane-bound organelles).As shown in the diagram of a plant cell, chloroplasts are bigger and fatter than mitochondria. A chloroplast is an organelle (found inside plant cells but not animal cells); a chloroplast is not a cell. For more about cells: the structure of a plant cell, the structure of an animal cell & comparison of plant, animal and bacterial cells.

Do plant cells contain mitochondria? Rating Newest Oldest. Best Answer: Plant cells contain chloroplasts as well as mitochondria. You're correct that photosynthesis occurs in the chloroplasts. Chloroplasts are present in order to produce glucose via energy from sunlight.The glucose is then transferred to the mitochondria where aerobic respiration takes place. Chloroplasts generate ATP, but not enough to keep the cell functioning.The reason that you'll find mitochondria in plant cells is because mitochondria generates most of the ATP required for the cell to function. The fact that plants contain mitochondria does not mean that indoor plants don't contain chloroplasts.ou're correct that photosynthesis occurs in the chloroplasts.

The Evidence 1 Both mitochondria and chloroplasts have their own genome, and it resembles that of bacteria not that of the nuclear genome. 2  Both genomes consist of a single circular molecule of DNA.  There are no histones associated with the DNA.

These organelles are the mitochondria in animal cells and the mitochondria and chloroplasts in plant cells.

What is a chloroplast? Chloroplast is an organelle found in plants and algae cells where photosynthesis occurs. The chloroplast contains chlorophyll which is the light sensitive pigment that powers photosynthesis and other pigments. Chlorophyll gives the plant its green colour.A plastid containing chlorophyll, developed only in cells exposed to the light.he chloroplast contains chlorophyll which is the light sensitive pigment that powers photosynthesis and other pigments. Chlorophyll gives the plant its green colour.

DNA in a cell DNA in a cell. Eucariotic cells contain several organelles. The nucleus contains most of the DNA in a cell and this DNA is called the chromosomal DNA. It is separated from the rest of the cell (cytoplasm) by a double layer of membrane. The mitochondria, which have a role in the oxidative degradation of nutrient molecules, also contain DNA, called the mitochondrial DNA. Eucariotic cells that are capable of photosynthesis contain chloroplasts with chloroplast DNA.

Chloroplast New chloroplasts may contain up to 100 copies of their DNA, though the number of chloroplast DNA copies decreases to about 15–20 as the chloroplasts age. They are usually packed into nucleoids, which can contain several identical chloroplast DNA rings.

Biology book1 Click Here to return to the search form. If I'm remembering correctly, chloroplasts have their own DNA, too. Scientists believe that mitochondria and chloroplasts were primitive cells without nuclei (prokaryotes) that got inside of primitive cells with nuclei (eukaryotes) and then stayed there.o they came in with their own DNA, and now they still have some of their own DNA that carries the code for some of their own proteins. They also need some proteins coded by genes in the nuclear DNA. A woman scientist first suggested all this, Lynn Margulis.

What are three characteristics of prokaryotic and eukaryotic cells? They do not contain any membrane-bound organelles (such as chloroplasts, mitochondria, endoplasmic reticulum, etc) and do not have a distinct nucleus (ie: no nuclear membrane-so the DNA is floating around in the cytoplasm).When DNA is floating around in the cytoplasm, it is called a nucleoid.hey do not contain any membrane-bound organelles (such as chloroplasts, mitochondria, endoplasmic reticulum, etc) and do not have a distinct nucleus (ie: no nuclear membrane-so the DNA is floating around in the cytoplasm).

What are mitochondrial and chloroplast DNA? A cell can have different types of mitochondria (heteroplasmy) or same type of mitochondria (homoplasmy). Chloroplast DNA: Like mitochondria, chloroplast also contain circular double stranded DNA molecules. They too do not associate with histones.hloroplast DNA is a circular molecule of DNA located in chloroplasts (an organelle mostly in plant cells and other eukaryotic organisms that perform photosynthesis).

Cell The three organelles that contain DNA are the nucleus, mitochondria and chloroplasts. Organelles are membrane-bound subunits within a cell -- analogous to organs in the body -- that perform specific functions. The nucleus is the control center of the cell, and houses genetic information.

Dna is located in the nucleus and the cytoplasm (TRUE OR FALSE)? Rating Newest Oldest. Best Answer: FALSE-------- DNA is found in the nucleus and some in the mitochondria, but not the cytoplasm--it can't float around in the cytoplasm because of enzymes called nucleases which eat up DNA and RNA. This enzymes cannot fit through the nuclear and mitochondrial membrane. Source(s):ost of the DNA is in the nucleus, but a small amount is in the mitochondria, which are in the cytoplasm. In the case of green plants, DNA is also found in chloroplasts. Climate Realist · 5 years ago. Thumbs up.
